<p>This domain is often found adjacent to the DHH domain, found in the RecJ-like phosphoesterase family <db_xref db="INTERPRO" dbkey="IPR001667"/>, and is called DHHA1 for DHH associated domain. DHHA1 is diagnostic of DHH subfamily 1 members [<cite idref="PUB00005478"/>]. This domain is also found in alanyl tRNA synthetase e.g. <db_xref db="SWISSPROT" dbkey="P00957"/>, suggesting that it may have an RNA binding function. The domain is about 60 residues long and contains a conserved GG motif.</p> Phosphoesterase, DHHA1
